The site has learned that Apple will replace these with a single cable, which is known simply as the Apple AV Cable. The consolidated cable will support both component and composite output on the same cable.
More interestingly, PhoneNews.com has learned that the next generation of iPhone and iPod touch will offer at least one version of the iPhone and one version of iPod touch with an even higher resolution screen and capable of full HD video output.
Currently the iPhone and iPod touch do not exceed 480i and 480p (respectively) in terms of video resolution. However, the next iPhone and iPod touch will enable full HD playback, with 720p and 1080i output modes.
It is also believed that Apple will provide the ability for users to access their entire iTunes Library from the iPhone via Wi-Fi.
The end result is that a user can sit at their HDTV, using an Apple AV Dock and an Apple Remote, controlling their iPhone much as they do an Apple TV today. This ensures that a new iPhone owner will be able to purcase, for under $100, all the equipment needed to access (via the iPhone) all of their computer-stored HD content, on their HDTV.
